Hello everyone, in a class project, i would like to change the backing file of the current image opened with a particular path file.

I try differents functions i saw in the source code

- bdrv_change_backing_file

- bdrv_open

- bdrv_open_child

but no one work... from segmentation fault error to bdrv_attach_backing passing through parent->blocking_error, i don't know how to achieve what i want.
